no 91 in the State of Arizona.. if your car is stock.. your get a little knock, and your ecu compensates for the lower octane gas or if your modified you have a 91 tune..

There are places selling 100 octane out of the pump, in Tucson, and Sierra Vista for sure, but just 91, you can tune for it, just not as good as 93

so the solution is to tune the car for 91? man that sux, I'm thinking about moving to AZ but this is throwing me off a little...

91 only. And all fill stations are not created equal. I would stick w/ top tier detergent brands only. There are several fill stations around the valley that sell VP 100 octane. You can put a 2-3 gallons of 100 in per fill up and it will blend to 93 or higher. I did this with my STi during the summer months and it completely eliminated any knock.

Just came to AZ from CT and my car ran like shiiiiiiit. Had the tune modified for the elevation and 91 runs much better now.

Unfortunately no 93oct that I am aware. 100oct for sure, there is one station in Tucson that sells it and you can also get high octane race gas from various sources in Tucson as well as Phoenix but not 93 oCT from regular gas stations.
